Most times there is a sight glass in the liquid line. It should be clear. Clear would mean it's fully charged and all liquid is passing by or that is completely empty. If you see bubbles, it may need more Freon especially if it is nearly all bubbles. If only a few bubbles, the system probably has enough.
134a systems will NEVER have a clear sight glass. Freon 12 systems will. Doug
